Classes
struct	CWSoundEmitter
	One sound emitter (MCSE, 28 bytes): the client reads 0x1C bytes per entry — a sound-entry id and a position/size pair. More...
struct	CWSoundEmitterVanilla
	One pre-WotLK sound emitter (MCSE, 52 bytes): the full inline emitter parameters later folded into SoundEntriesAdvanced. More...
struct	MCNREntry
	One MCNR normal (3 signed bytes, x Z Y; 127 == 1.0). More...
struct	MFBOPlanes
	The flying bounding box (MFBO, BC+): two 3x3 grids of int16 heights — a maximum plane you fall through and a minimum plane below the world. More...
struct	MHDRData
	The tile header (MHDR, 64 bytes, root/monolithic). More...
struct	SLVert
	One legacy liquid vertex (MCLQ, 8 bytes). More...
struct	SMChunk
	The per-cell MCNK header — 128 bytes, memcpy'd verbatim. More...
struct	SMDoodadSetRange
	One Shadowlands doodad-set range (MWDR): a [begin, end] span into MWDS. More...
struct	SMLayer
	A per-cell texture layer (MCLY, 16 bytes). More...
struct	SMTerrainMaterial
	One MCMT terrain-material record (Cata+): a TerrainMaterial id per layer. More...
struct	SMTextureColorGrading
	One MTCG color-grading record (Shadowlands+): the color-grading LUT FileDataIDs for the same-index diffuse texture. More...
struct	SMTextureFlags
	One MTXF texture-flags record (WotLK+): flags for the same-index MTEX texture. More...
struct	SMTextureParams
	One MTXP texture-parameter record (MoP+): the MTXF flags plus the _h height-texture scale/offset that drive height-based blending. More...
struct	SMVert
	The magma/slime reading of an MCLQ vertex (8 bytes): two u16 texcoords and the shared height. More...
struct	SWFlowv
	One legacy liquid flow vector (MCLQ SWFlowv, 40 bytes). More...
struct	UVMapEntry
	One MH2O UV texture-coordinate entry (two u16, divided by 8 in shaders). More...

Detailed Description

ADT chunk binary structs (the MCNK cell header, texture layers, liquid records, flying bounds) and their flag enums.

Enumeration Type Documentation

LayerFlags

enum class wowlib::formats::adt::chunks::LayerFlags : std::uint32_t

strong

Per-cell texture-layer flag bits (SMLayer.flags).

The low 6 bits hold the animation rotation (0x7) and speed (0x38); see SMLayer.animation_rotation()/animation_speed().

Enumerator
AnimationEnabled	Texture-coordinate animation is on.
Overbright	Render much brighter (used for glowing lava).
UseAlphaMap	This layer blends through an MCAL alpha map (set on every layer after the first).
AlphaMapCompressed	The layer's MCAL alpha map is RLE-compressed on disk. wowlib decodes it either way; on write it re-compresses when this bit is set.
UseCubeMapReflection	Treat the ground layer as a skybox reflection (needs an MTXF entry).
unknown_0x800	WoD? with 0x1000: apply the texture-effect texture scale.
unknown_0x1000	WoD? +; see 0x800.

LiquidVertexFormat

enum class wowlib::formats::adt::chunks::LiquidVertexFormat : std::uint16_t

strong

Enumerator
HeightDepth	Case 0: a float height map and a byte depth map (the pre-WoD go-to).
HeightUv	Case 1: a float height map and a UV texture-coordinate map.
DepthOnly	Case 2: a byte depth map only; the surface is flat at 0.0 (ocean).
HeightUvDepth	Case 3: a float height map, a UV map and a byte depth map.

Definition at line 19 of file liquid.hpp.

MapChunkFlags

enum class wowlib::formats::adt::chunks::MapChunkFlags : std::uint32_t

strong

Per-cell MCNK header flag bits (SMChunk.flags).

Enumerator
HasMcsh	The cell has a baked shadow map (MCSH sub-chunk).
Impassable	Impassable terrain (no walking).
LqRiver	Legacy (MCLQ) river liquid present.
LqOcean	Legacy (MCLQ) ocean liquid present.
LqMagma	Legacy (MCLQ) magma liquid present.
LqSlime	Legacy (MCLQ) slime liquid present.
HasMccv	The cell has vertex colors (MCCV sub-chunk, WotLK+).
unknown_0x80	Unknown (0x80).
DoNotFixAlphaMap
HighResHoles

Definition at line 24 of file header.hpp.

MapHeaderFlags

enum class wowlib::formats::adt::chunks::MapHeaderFlags : std::uint32_t

strong

Tile header flag bits (MHDRData.flags).

Enumerator
HasMfbo	The tile has a flying bounds chunk (MFBO).
Northrend	Set on some Northrend tiles; meaning unknown.
